Co-Payments Go Way Up for Drugs With High Prices

Health insurance companies are rapidly adopting a new pricing system for very expensive drugs, asking patients to pay hundreds and even thousands of dollars for prescriptions for medications that may save their lives or slow the progress of serious diseases.

With the new pricing system, insurers abandoned the traditional arrangement that has patients pay a fixed amount, like $10, $20 or $30 for a prescription, no matter what the drug's actual cost. Instead, they are charging patients a percentage of the cost of certain high-priced drugs, usually 20 to 33 percent, which can amount to thousands of dollars a month.

The system means that the burden of expensive health care can now affect insured people, too.

No one knows how many patients are affected, but hundreds of drugs are priced this new way. They are used to treat diseases that may be fairly common, including multiple sclerosis, rheumatoid arthritis, hemophilia, hepatitis C and some cancers. There are no cheaper equivalents for these drugs, so patients are forced to pay the price or do without.

Insurers say the new system keeps everyone's premiums down at a time when some of the most innovative and promising new treatments for conditions like cancer and rheumatoid arthritis and multiple sclerosis can cost $100,000 and more a year.

But the result is that patients may have to spend more for a drug than they pay for their mortgages, more, in some cases, than their monthly incomes.

The system, often called Tier 4, began in earnest with Medicare drug plans and spread rapidly. It is now incorporated into 86 percent of those plans. Some have even higher co-payments for certain drugs, a Tier 5.

Now Tier 4 is also showing up in insurance that people buy on their own or acquire through employers, said Dan Mendelson of Avalere Health, a research organization in Washington. It is the fastest-growing segment in private insurance, Mr. Mendelson said. Five years ago it was virtually nonexistent in private plans, he said. Now 10 percent of them have Tier 4 drug categories.

Private insurers began offering Tier 4 plans in response to employers who were looking for ways to keep costs down, said Karen Ignagni, president of America's Health Insurance Plans, which represents most of the nation's health insurers. When people who need Tier 4 drugs pay more for them, other subscribers in the plan pay less for their coverage.

But the new system sticks seriously ill people with huge bills, said James Robinson, a health economist at the University of California, Berkeley. ''It is very unfortunate social policy,'' Dr. Robinson said. ''The more the sick person pays, the less the healthy person pays.''

Traditionally, the idea of insurance was to spread the costs of paying for the sick.

''This is an erosion of the traditional concept of insurance,'' Mr. Mendelson said. ''Those beneficiaries who bear the burden of illness are also bearing the burden of cost.''

And often, patients say, they had no idea that they would be faced with such a situation.

It happened to Robin Steinwand, 53, who has multiple sclerosis.

In January, shortly after Ms. Steinwand renewed her insurance policy with Kaiser Permanente, she went to refill her prescription for Copaxone. She had been insured with Kaiser for 17 years through her husband, a federal employee, and had had no complaints about the coverage.

She had been taking Copaxone since multiple sclerosis was diagnosed in 2000, buying 30 days' worth of the pills at a time. And even though the drug costs $1,900 a month, Kaiser required only a $20 co-payment.

Not this time. When Ms. Steinwand went to pick up her prescription at a pharmacy near her home in Silver Spring, Md., the pharmacist handed her a bill for $325.

There must be a mistake, Ms. Steinwand said. So the pharmacist checked with her supervisor. The new price was correct. Kaiser's policy had changed. Now Kaiser was charging 25 percent of the cost of the drug up to a maximum of $325 per prescription. Her annual cost would be $3,900 and unless her insurance changed or the drug dropped in price, it would go on for the rest of her life.

She needed the drug, she said, because it can slow the course of her disease. And she knew she would just have to pay for it, but it would not be easy.

''It's a tough economic time for everyone,'' she said. ''My son will start college in a year and a half. We are asking ourselves, can we afford a vacation? Can we continue to save for retirement and college?''

Although Kaiser advised patients of the new plan in its brochure that it sent out in the open enrollment period late last year, Ms. Steinwand did not notice it. And private insurers, Mr. Mendelson said, can legally change their coverage to one in which some drugs are Tier 4 with no advance notice.

An article on Monday about a large increase in insurance co-payments for high-priced drugs misstated the way the multiple sclerosis drug Copaxone is administered. It is injected, not taken in pill form.
